TYPE-WRITING MACHINE@ SPECIFICATION forming part of Letters Patent No. 655,652, dated August '7, 1900l Original application filed November 8, 1892, Serial No. 1151.412. Divided and this application filed .Tune 10, 1896. Serial No. 594,931. (No model.)

To aZZ whom in' may concern: p Be it known that l, JONATHAN O. FowLER, J r., a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a certain new and useful Type-Writing Machine, of which the following is a specification, the same" beingV a division of my application filed November 8, 1892, Serial No. 451,412.

My invention relates to type-writers having a plurality of keys, and has for its object the provision of features of novelty whereby a type-writer comparatively simple in construction, inexpensive in manufacture, and efficient in practical use may be organized.

To attain the desired end, my invention consists in the construction, arrangement, and operation of parts herein set forth.

In the drawings which form a part of this specification, Figure l represents a side elevation, partly in section, of my type-Writer; and Fig. 2 is a similar view, one of the keys being depressed. Fig. 3 is a plan view of the` ends of my type-carriers, and Fig. 4 is a view in detail of one of my keys.

Like letters of reference indicate like parts in all the views.

Referring particularly to the drawings, A and C denote two of my manual vertical keys sustained in normal position in any suitable manner, as by springs D, each key being provided with working or movement-impacting means, as the enlarged lower portion a c, having an inclined lower edge. Intermediate a suitable type-carrier constructed according to my invention, as the radially-disposed reciprocating type-carriers E, traveling in radially-disposed guides and Working in the same and preferably-horizontal plane, andthe hereinbefore described preferably vertical keys, as A and O, is located suitable coacting mechanism, consisting in this instance of the following parts, which I term engaging mechanism The type-carrier rod e is loosely supported by suitable bearings within the frame or case of my typewriter and is furnished at its free end with the type-carrier proper, E, provided with type-faces (12.02 and with recesses cd2 02, located under or rearward of the same. The reciprocating or sliding horizontal bar F is also suitably supported,

by means of the spring Mpcommon to the two keys and serving to resist the forward stroke of the type-carrier with an increasing tension, the Shanks of the keys preventing the forward movement (beyond the normal position) of the same.

A flat pivoted rocking lever G, provided with slots at both extremities, is fnlcrumed at g and connected ina movable relation with the forward free extremity of the bar F by `the stud or roll f2 within its lower slot or groove, and is provided at its upper end with an enlargement or disk, through which thc stud or roll Z2, forming the end of the spring L, carried by the type-carrier, passes. The pivoted rocking part G thus has a lower slot to engage a studor roll f2, actuated by one of the keys, and is also adapted to enga-ge and actuate the type-carrier with a stud or roll and groove movement. Intermediate the type-carrier head or block E and the disk of the lever G, I preferably place a flexible connection, consisting in this instance of a spiral spring L, passing around the type-carrier rod e and located between the lever G and the type-carrier block E.

It will be observed that the working portions of the keys are constructed and arranged to descend and rise again in a vertical line and in one plane. Each key is thus provided with projecting and recessed portions constructed and arranged to move vertically-as, for instance, the enlarged lower portions a of the said key. Each such projectingand recessed mechanism is also con structed and arranged to become engaged upon the manipulation of the key, as follows: Whenever a key is depressed, the enlarged portion a engages a stud or roll f of the bar F, thereby moving the same to the right or backward, the lever G being thereby rocked, which lever bears against the spring I., thus causing the type-carrier E e to move forward or to the left. In order that the depression IOO y of the different keys may cause a different let.-

ter to be printed when my key-action is used with the other mechanism herein shown, I provide a stop device controlled by the keys, whereby the movement of the type-carrier may be regulated, which stop device consists in the present instance of the pin e' of the type-carrier rod c and the arms ct c', respectively connected with and controlled by the keys A and C. The vertical arms d c serve as stops for the type-carrier, and in order to secure means for insuring the retention of the type-carrier in'one of its limited differential forward positions as long as any key is depressed I provide means, as the closed tops a4 c4 of the arms a c', the said tops also serving to connect the said arms with the keys, which closed tops prevent some of the keys from being depressed sufficiently far for the arms d c in descending to pass by or away from the stop, as the pin e of the type-carrier rod e, and which tops therefore serve as retaining means in connection with the arms a' c to hold the pin e' adjacent to the said arms a c and hinder the type-carrier head E from moving from its printing position as long as any key is depressed.

The type-carrier E e is not only prevented from advancing beyond the required printing-point by reason of the arms a c being in the path of the forward movement of the stopping-pin c, but is also prevented from receding by reason of the engagement of the impacting faces of the enlarged lower portions a c of the keys A C with one of the studs or rolls f of the bar F, which holds the type-carrierE e forward, acting in connection with the rocking lever G. The arms a' c', used in connection with the enlargements a c', thus prevent the type-carrier from moving in either a forward or rearward position from the printing-point.

Inasmuch as more than two keys may be used in my type-writer it is manifest that similar or equivalent means may be used for operating whatever number of type-carriers it may be deemed advisable to embody in a machine. For example, a series of radiallydisposed type-carriers provided with three type-faces are shown in Fig. 3, each of which type-carriers may be actuated by three keys, constructed and arranged to operate the same in a manner similar to those described herein. I provide my machine with a common center gateway or printing-aperture J, preferably 'formed in a yielding plate, as of soft rubber,

so that each individual type on each typecarrier when in alinement with the aperture can be thrust up to engage the paperon the platen'. This aperture .I is located in `front of the type-carriers and in the same vertical plane with each type-carrier, the type-faces of the radially-disposed type-carriers being inclined as regards their longitudinal axes so as to come into proper alinement when at the printing-point. IVhen a key, as C, is depressed by such depression or initial movement, the enlargement c causes the type-carrier E e to advance by means of the intermediate stud or rollf, bar F, stud f2, lever G, and stud Z2 of the spring L. The continued depression of the key causes the arm c to engage the pin e/ of the type-carrier rod, whereupon the type-face c2 will be positioned immediately below the printing-slot J.

Inasmuch as the type-carrier E e is prevented from moving forward by the stop e it is manifest that the stud or rollf may either move along the vertical shank of the enlargement c, if the key is pushed down farther, or

yelse that the depression of the key may-cause the hammer K to be operated by the pin c3 of the arm c', the additional movement of the bar F and rock-lever Gcausing the compression of the spring L. By means of the engagement of the pointed head of the hammer K with the recess c12 of the type-carrier E the corresponding character c2 may be imprinted upon the paper on the platen.

It is manifest that various omissions of some particulars could be made without materially affecting the essential features of my invention or the operation of the remaining parts, and I do not therefore wish to be limited to the specific structural details of the organization herein set forth. Obviously, the elements of the structure described may be located at an angle to the plane in which they are shown or they may be inverted, if desired. I accordingly use the words vertical, horizontal, and the like in a relative sense.

A"The relative positions of and the method of impacting the type faces and platen and also the location of the type-faces upon the typecarrier may be varied, and any desired style of platen and paper-carriage may be employed, and although only two keys are shown yet any one skilled in the art will be enabled to construct according to my invention a machine consisting of any required number of keys. p

In this application I only claim the key-action, the other features shown and described being claimed in my application tiled November S, 1892, Serial No. 451,412, of which this is a division.

As it is evident that many changes in the construction and relative arrangement of parts might be resorted to without departing from the spirit and scope of my invention, I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such changes and equivalents inay be substituted therefor, and that Vhat I claim as my invention isl.
